Thanks for your reply. I did download the latest software for Flash Player as well as Adobe Reader. However I am not 100% sure if it has defaulted to use the latest or whether files are still using old systems?

Hi Vansmith
I can forward an email which has an attachment that cannot be opened. The same email sent to a Window machine opens fine. Also tried saving attachment and then opening and it is just gibberish.
Second example is our Tax Receiver has an online site where you submit online submissions of tax returns. Docs can be open in either PDF and in Flash. Flash ties to load and opens the border of the page where you see headers and footers but no content. PDF opens a blank page and even if you wait 10-15 minutes does not load. Same program on Windows works fine in both Flash and PDF.
So problem lies with my Apple Setup relating to how Flash and PDF has been loaded. I have uninstalled both and re-loaded with latest yet problem persisits.
